| One was dextrorotatory when dissolved in aqueous solution, the other was levorotatory. |
|
| The chemical structure of the natural form of ephedrine is levorotatory, while the synthetic ephedrine is a racemic mixture. |
|
| Morphine is an amphoteric pentacyclic alkaloid that exists naturally in its levorotatory form as columnar colorless prisms. |
|
| Basic amino acids, which have a pH above 7, are transported at about 5 to 10 percent of the rate of neutral levorotatory amino acids. |
|
| In fact, levorotatory amino acids are absorbed almost as quickly as they are released from protein or peptide. |
|
| Foliar Fertilizer: This highlights products for foliar applications that feature safety of use, due to the low molecular weight and the presence of amino acids primarily in the levorotatory form. |
|
| One compound, a racemic mixture of two enantiomers, dextro-rotatory clopidriogel and levorotatory clopidriogel, was of particular interest to Sanofi. |
|
| Levorotatory amino acids are absorbed extremely rapidly much more rapidly than are dextrorotatory amino acids. |
